Appsman0428 great job on the install, very creative and great timing for me as my Airhead toilet in being packed for shipping.
I thought about that location as well but couldn't figure a way to end up with the fan motor anywhere that would be easy to replace. I think I have settled on entering the bathroom cabinet at the floor behind the kick plate and installing it in the floor next to the wheel well. That location leads to the underbelly and should be protected from any type of airflow that would create blowback. In addition to the hole for the hose to enter the wall, I'll need to cut an access panel on the bottom shelf in the bathroom cabinet that will allow me access to that area for mounting the fan to the floor. I'll pick up the power directly from the distribution panel I plan to put it on it's own fuse. I wanting to put my
12v fridge on it's own fuse as well and it will be a good time to do both of them while I have the distribution pulled out.
